PR Summary

Add a new PSNativePSPathResolution Experimental Feature where if a PSDrive is passed to a native command and uses the FileSystem provider, then the resolved file path is passed to the native command. This means something like:

code temp:/test.txt

now works as expected. Also, on Windows, if the path starts with ~, then that will get resolved before passing to a native command. In both cases, the path is normalized to the directory separators for the relevant operating system. Note:

• if the path is not a psdrive nor ~ (on Windows), then path normalization doesn't occur
• if the path is in single quotes, then it's not resolved and treated as literal
